I was scammed from craigslist for a Dell ultrasharp 19" LCD monitor. It appears the backlight is out (i get the green power on/signal received LED, but no signal on monitor (the "no signal" icon doesn't even show up)...so im assuming the backlight is out.

back in the day, i remember reading that it was so expensive, you might as well just buy another/new LCD... but what about today?

is it possible to do backlight repairs easily? should i bother contacting dell to see if they can repair?

id love to get this running; i love the dell ultrasharps and would like to match my existing monitor

thanks,
 
Boot up, shine a flashlight onto the screen if you see the Windows logo (or whatever OS's logo you are using), then that means the backlight is shot.

Call a local repair shop and ask for an estimate.
 
How do you get scammed on craigslist for an lcd? You didn't meet the guy in between and not tested before buying right?
 
If you don't mind aesthetics, ghetto mod in some white ccfls to where the originals were. You will first need to take the panel apart (small little screws and bent metal tabs) and see how long the tubes are, how thick they are and how many - then just get something similar from your favorite computer modding store. If you are lucky and I mean lucky (in that you manage to get new tubes/inverter with specs equivalent to the originals) you may even be able to run it from the original inverter if that isn't shot or run the original ccfls from new inverter.

However, take extra precautions as ccfls do run on 600-1000V or even more, inverters have been known to catch fire, they can get really hot, frayed wires can cause nasty or even lethal shocks, fry your circuitry, etc!

Look its not that hard of a job I've done it myself. Look up on ebay for replacement lamps and you will find venders selling replacments for any type of lcd out there the hardest part is not breaking the ones in laptops they are thin as string and easily broken they don't cost much buy and extra incase you do break one there are 2 in all desktop lcd panels but if you see nothing at all when booted up prob is the inverter board you can get that from ebay as well. easier fix than the lamps!

The job takes patience and time!
